Figure 1: Schematic diagram showing diagnostic criteria for using diffusion-weighted imaging for staging bladder cancer. Cancer component, muscle layer, and submucosa show high, intermediate, and low signal intensity, respectively. Submucosal stalk or thickened submucosa indicates T1 or lower stage; smooth tumor margin without submucosal components, T2; irregular margin toward the perivesical fat tissue, T3; and extension into adjacent organs, T4 [6].
